907-0601-00 Rev. C
3.1.1 Remote Multiplexer Card (907-R)
Card P/N
Config. Dwg.
Diagnostics:
The 907-R is the remote half of the multiplexer motherboard set. Optical fiber routing may vary from assembly
to assembly, however a fiber bend radius of more than 16 mm should be maintained at all times. The remote
units may be configured with no WDM, with a singlemode WDM, or with a multimode WDM. Fiber access is
typically via an ST/PC bushing in the middle of the card, though FC/PC options are available. If no WDM is
required, fiber inputs and output fibers are connected directly to the optical transceiver Rx (receiver) and Tx
(transmitter) ports. A 907-R configuration using a WDM is shown in Figure 3-4.
All three SMB video connectors have a 75-ohm input impedance. The input video signals are streamed
through the optical link to the output video connectors of the 907-C card. Three 8-pin Molex connectors are
used for the six bidirectional data channels.
3.1.2 Console Multiplexer Card (907-C)
Card P/N
Config. Dwg.
Diagnostics:
The 907-C is the console half of the 907 motherboard pair and as with the 907-R, fiber access is typically via
an ST/PC bushing in the middle of the card, though FC/PC options are available. A 907-C configuration using
a WDM is shown in Figure 3-4. The 907-C has video connector outputs and the 907-R has video connector
inputs.
All three SMB video connectors have a 75-ohm output impedance (AC-coupled) and provide the output video
received from the input video connectors of the 907-R card. Three 8-pin Molex connectors are used for the six
bidirectional data channels.
